Gentlemen I just took the plunge and put a DPMS carbine on lay away. I spoke to the salesman and he stated that it was interchangable with bushmaster parts and has a 1:9 twist. Since he didnt have a bushmaster and the price was good for what I found I figured I couldnt resist. He sold it to me for 794.00 NIB> with tax it came to 834.00. I plan on buying a match barrel in 24 inch with a flat top for some serious varmiting. My questions are what do you guys know about this type of rifle good or bad. What are some spare parts that I should purchase for this as in maintenance items. Any other information is a plus. Thanks for your help. Esox357 Wanna kill these ads? We can help!
